Title: Minute clearance measuring instrument
Inventor: TANAKA YOSHITO
IPC: G01B11/14
Filed: 1986-02-24
Abstract: PURPOSE:To improve measuring accuracy of a minute clearance by vapor depositing a reflection film of a magnesium fluoride on the under surface of a head for measurement and almost equalizing the reflected light intensity on the under surface of the head for measurement with that of the magnetic disk surface and making interference fringes distinct. CONSTITUTION:Incident light 2 from a light source 1 is reflected on a beam splitter 3 and irradiated on the surface 6a of a flexible magnetic disk 6 through the translucent head 4 for measuring the minute clearance. Then, the reflection film 5 of the magnesium fluoride is vapor deposited on the under surface of the head 4 for measuring the minute clearance in order to increase the intensity of reflected light beams 2a of the light beams 2. In this way, the interference fringes are made distinct and the measuring accuracy is improved by almost equalizing the reflected light intensity on the under surface of the head 4 for measuring the minute clearance with that on the surface of the magnetic disk 6. Further, the minute clearance can be continuously measured by moving the head 4 for measurement along the diameter of the magnetic disk while turning the magnetic disk 6 and observing it with a microscope 7.
